Estimating the term…
A sensor arrangement (1) for measuring a pressure and a temperature in a fluid is disclosed. The sensor arrangement (1) comprises a temperature sensitive electrical element (3) and a pressure sensing electrical element (6), the temperature sensitive electrical element (3) and pressure sensing electrical element (6) are both coupled to one side of a metallic membrane structure (4,16). The metallic membrane structure is arranged to pass on the temperature of the fluid which is at the other side of the membrane structure (4,16) to the temperature sensitive electrical element (3) and to pass on the pressure in the fluid to the pressure sensing electrical element (6). In this way a combined pressure and temperature sensor is obtained which is applicable in vehicle air-conditioning systems working with CO2 as refrigerant.
A sensor arrangement (1) for measuring a pressure and a temperature in a fluid, the sensor arrangement (1) comprising a common body (11, 12, 14), a membrane structure (4, 16), a temperature sensitive electrical element (3) and a pressure sensing electrical element (6), the temperature sensitive electrical element (3) and pressure sensing electrical element (6) are both coupled to one side of the membrane structure (4, 16), wherein the membrane structure (4, 16) comprises an elongated body (16), at a closed end (15) of the elongated body is located the temperature sensitive electrical element (3) and close to an open end (17) is located the pressure sensing electrical element (6). wherein an axial movement of the elongated body (16) influences an electrical property of the pressure sensing electrical element (6).
